Abstract:
Objective To explore the aging changes of facial soft tissue of adults in the natural state without orthodontic treatment within 2 years.
Methods A total of 61 college students, including 28 males (26.2 ± 2.2) years old and 33 females (25.2 ± 2.3) years old, were enrolled. The three-dimensional facial data were captured using stereoscopic tomography technology at the initial (T0), 12 months (T1), and 24 months (T2), and overlapped. The facial part was divided into 11 regions, including bilateral infraorbital region, cheekbone region, zygomatic region, sub-zygomatic region, paranasal region, upper buccal region, lower buccal region, upper cheilion region, lower cheilion region, mandibular angle region and temporal region. Qualitative and quantitative analysis of absolute color mapping for different regions of the overlapping image was carried out. Data were analyzed using group t test.
Results Within 2 years, the overall and regional area changes of facial soft tissue of male and female were all within the range of systematic error, and there was no statistical significance (P>0.05). At T1-T0, there was no statistically significant difference in the overall facial area and regional changes between males and females (P>0.05). At T2-T0, there was significant difference in the changes of the zygomatic region (male 0.134 ± 0.461 mm, female 0.073 ± 0.461 mm) between males and females (t = -2.121, P = 0.038), but there was no significant difference in the changes of the other facial regions (P>0.05) .
Conclusion In two years of the natural condition, the aging changes of the facial soft tissue of adults aged about 25 years old were limited.
